About this part

Product Details

Cometic Gasket has built a reputation for making solid Multi-Layer Steel (MLS) head gaskets, and this particular one is designed for Chevrolet Gen-1 Small Block V8 engines. If you're rebuilding or refreshing the top end of your engine, a good head gasket is crucial for sealing the combustion chamber and coolant passages. This gasket features a compressed thickness of .060 inches and a bore size of 4.030 inches, making it suitable for a wide range of applications, including those with aftermarket heads where water ports might be undersized for customization.

What sets these MLS gaskets apart is their construction. They're made from multiple layers of stainless steel, which gives them strength and the ability to rebound, helping to resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes, ensuring a reliable seal even under high output conditions. This design means you don't need to use any extra sealants, and they work well with both aluminum and cast iron blocks, handling the forces created when different metals are joined.
